I would appreciate any thoughts on any double buggy, I need a side by side, it has to be very very easy to push as I live in a very hilly area, it needs to be able to take a buggyboard and most importantly it needs to be light enough and easy to steer using one hand as I will have a walking toddler who may or may not use the board depending on how far we walk. The pushchair will be used for a 12 month old and a 16 month old. I have looked at and really like the baby jogger city mini but I'm open to any other ideas. Many thanks.
